Figure 3 is a bottom plan.

rlhe device forming the subject matter of this application preferably is made of metal, and includes a tubular receptacle 1, embodying a barrel 2. A suspension bail 3 extends downwardly within the upper end of the barrel 2 and is held upon the barrel, removably, by means of a securing device, such as a bolt 4, mounted in the lower cnd of the bail 3 and in the upper` end of the barrel 2. A tubular foot 5 is provided, and the lower end of the barrel 2 extends downwardly within the upper end of the foot Securing members 6, such as screws, hold the foot 5 on the lower end of the barrel 2. The foot 5 is provided with an internal shoulder 7, against which the lower end of the barrel 2 abuts, so as to take some ot the strain off the screws or securing elements 6. The tubular foot 5 is considerably thicker than the barrel 2. rlhis construction is rcsorted to in order to add weight, and to pio vide a secure place et' mounting for sundry movable parts which will be alluded to hereinafter. end with a notch 8, and a pivot element 9 extends across the notch 8, the pivot element being mounted at its ends in the foot 5. A notch 10 is formed in the lower end of the foot 5 and is disposed opposite to the notch 8. The notch 10 communicates with a superficial longitudinal groove 11 formed in the Y r -Y i. i fashionedjin the :toet4 5 andfcommunicate It is within the f provinceA ofthe disclosure 1 'residesn g the icombina- Y devicelglconstructed in' accordance 'with' the The foot 5 is provided in its lower` Amen. www tiibleiss, ,F Caelirsfelrilwasf naaien, .f

The construction is such that the latch 17 can tilt in the direction of its length on the fulcrum member or screw 18, but the latch 17 cannot swing laterally on the fulcrum member or screw 18, because the latch is held by the head of the screw 18, in the longitudinal groove 11. In the upper end of the latch 17 is mounted an adjustable stop19, such as a screw. adapted to engage the foot 5 at the base of the groove 11. The screw 18 may be threaded in or out, as occasion may require, to limit the amount that the latch 17 tilts. It is desirable to limit the amount that the latch 17 tilts, so that the lower end ot the latch will not swing outwardly, or to tluA lett in Figure 1, too Vliar and catch on external objects. A compression spring 2O is mounted in the seat 12 and bears against the latch 17 at a point adjacent to the lower end ot' the latch. On its extreme lower end, the latch 1.7 is supplied with a hook-shaped part 21, the bill of which extends upwardly, 'for engagement with the depending bill on the part 16 of the retainer 14.

In practical operation, the retainer 14 is raised into the horizontal position of Figure 1, and the hook-shaped part 16 of the retainer 14: is engaged with the hook-shaped 21 of the latch 17. The latch 17 thus, is prevented from swinging outwardly at its lower end, under the impulse of the spring fili curing element or bolt 4 is removed, together with the suspension bail 3, andnthe charge 22 is placed iii-Lthe"barrel:2;I- 'lhe's'eeu'ring slugs, like the member 22, and these elements'A 22; are low-eredone at atime. vYhe-jn thedevice, arra ed-asishown in-solidfkline in- E igureloft 'e dra-Wings, hasr been lowered falyenoughfinto ythe Well, the 'projection- 15j onfthe-retainei'l comes int-o Contact with thecliargeivvhich has already beenldeposited inythe -vvell, and pwvingto the Weight`ofythe' device show-n'in Figure-Q1, the receptacle l moves'downvvardlvjwith respectto-t'he re` the retainer ltj'is disengagedfromthe hookshaped part-2l of the latclifl?.
